....an established character dies in an action film, is then greeted by a brief "oh no!" by the remaining cast, but then they're back at cracking jokes and acting as if nothing ever happened five minutes later?

almost every movie the phone number starts with 555, that makes me laugh and if they are in the woods, the actors are almost always PERFECTLY lit, but even when they are perfectly lit, their characters are acting like they can't see and such.

EDIT, actually these things I don't hate as the subject suggests, I just think they are funny!!!
